Fix the following error seen on MacOS:
/usr/bin/awk: syntax error at source line 22 source file
header_pattern = >>> @ <<< /^[A-Z][[:alnum:]-]+:/
The @ character in front of regular expressions to pre-compile them
seems not in the POSIX specification. Replace them with regular strings
and call match() instead of the ~ operator.
Also, adjust the url_pattern expression for BSD awk which explicitly
states:
The awk utility is compliant with the IEEE Std 1003.1-2008 (“POSIX.1”)
specification, except awk does not support {n,m} pattern matching.
Use [[:lower:]]+ instead of [a-z]{2,6}.
Tested with:
GNU Awk 5.1.1
awk version 20121220 (FreeBSD)

Diff chunks can occur in the middle of email conversations followed by
regular and/or quoted text. Handle that properly.
Change diff meta lines inside quotes to bold. Update the meta lines with
more combination for renamed, copied and deleted files.
Fix the diff_chunk invalid color code, only colorize the chunk
characters, not the whole line.
Remove redundant variable resets to 0.

Fix parsing of colons. Since the field separator is also the colon, it
could mess up the parsed fields, i.e. a subject line like "WG: dinner"
could end up as "WG" instead of keeping the entire string.

Rewrite of the awk calendar filter to make it posix compliant. Tested
with awk --posix (awk -V = GNU Awk 5.1.1). Also added some improvements
to readability and formatting.
This complements commit 3ef4a3ca05 ("filters: try and make awk scripts
posix compliant").

\x escape sequences are GNU specific. Use the octal escape code instead.
filters/calendar is beyond help. It would need a complete rewrite to
make it work with POSIX awk.

Add those to be correct and consistent.
Additionally, remove the vim comment, it's unnecessary.

When a signature contains a line that starts with an url, the url is not
highlighted properly:
--
Foobar
[38;2;255;255;175mmhttps://foobar.org
The trailing m of the signature color start \x1b[38;2;175;135;255m is
considered as part of the URL scheme (i.e. mhttps:// instead of
https://). Colorize the URLs first before wrapping with the signature
color.

Python is not available on all systems. Port the colorize filter to awk
as it is a more widespread POSIX utility.
Users are free to copy the filter into their home dir and tweak the
colors to their needs. The highlighted items are:

Item Red Green Blue Color

Presumably some email servers will transform newlines into carriage
return new lines to better support windows users. I can't prove this but
that's the best explanation I have for my hosted email provider
(fastmail).
Without this patch, I was seeing annoying `^M`s at the end of every

I was getting errors when using the hldiff filter with aerc
because the plus symbol on line 28 wasn't escaped. This commit
